You probably noticed and have been wondering why so many Olympians from numerous events have masses of tape adhered across various body parts. It's called Kinesio Tape and was developed by a Japanese chiropractor to help heal injuries and and boost performance.
Kinesio claims to cut pain and boost performance. And judging by its prominence at this year's Games, athletes think it works.
"If you don't know the proper taping technique, you're not going to get the results you want," said Good, adding that more than 100,000 athletic trainers worldwide have taken the paid Kinesio Taping course, about 10,000 last year in the United States alone.
